EMIL'A. NELSON,` 0F DETROIT, MIHIGN, AssIGNoR To HUPP Moron. CAR coMrANY, j

T all whom it .may concern Be itknown that'I, EMIL A.y NEnsoN, a citizen of'the United States of America, re-

siding at. Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements 1n Lubricating Systems for- Engine and Transmisings I I concentric with sion, of which the following isA a specifican to the accompanying drawings.

The invention relates to engine and transmission constructions and has more particular reference to the means employed for lubricating parts of the mechanism as-hereinafter setforth. -In the drawings,-Figure l is a longitudi- Vnal section, partly in elevation; and Fig. Q

, is a cross section on line -m Fig. 1.

'A is the engine shaft, B the iy wheel mounted thereon, C a transmission shaft 1n axial alinement with the engine shaft, and D the propeller shaft which is coupled by a univer'sal ball and socket couplingto the shaft.'

C. The iiy wheel and transmission shaft C are mounted-in a casing F which-is in. open communication with the crank case ,and which includes in addition "to the parts menti oned a suitable variable speed transmission gearing (notshown). At the end of this case F is ajournal bearing G for the shaft' n and beyond said case is a housing H for theA propeller shaft which has auniversal joint formed by complementary spherical bear* the universal joint of the shafts C and D. i

` During the operation of the engine the mechanism within the housing Fis lubricated by any sui-table lubricating system such for-instance as the usual splash system Where the lubricant is thrown up by the -revolving cranks. The lubricant thus applied will force its way to, the various running parts within the case F, the bearing G, and

l will further pass through said bearing and into the universal joint of the, shafts. It is desirable however, to'prevent the further How down the inclined propeller shaft or through the housing .H therefor and to this end I devised theafollowing'construcl tion.:

The universal Vjoint between the shafts C and D is formed by a ball E on the shaft C anda cup-shaped socket J having-itsneck portionsecured to the propeller shaft. The socket J is constructed to form a cup` having socket lprovided with a 4CORPORATION or l MICHIGAN. LUBEICATING SYSTEM FOR ENGINE AND TRANSMISSION;

imperforate sides andfiiares outward within the spherical portion of the universal joint Ia I. This cup-shaped soclget receives the lutween the shafts and Whenthe supply within the cup-shaped member overiiows', the lubricant` instead ofrunning downthe propeller shaft will drainto the' center of the spherical bearing I. This accumulation is then removed`by a drain'conduitlK which has one end communicating with the interior of the portion I through alining apertures L and- Mjin 'the bearings-I I and which .inclines downward into the porti/on of the housing F l adjacent tothe fly-I vheelpand has its discharge end in proximity to said wheel.

Preferably the socket J is formed of two parts, a member N which .with themembc'r E'forms a universal joint of standard construction, and--a member O of configuration Complementary to the member N butlhaving imperforate sides so as toprevent the lubricant from discharging from .the socket J eXceptgby overflowing at the flared end thereof. i 'In operation the rotation ofthe lfly wheel B laterally past the end of the-drain conduit K will act as a pump, sucking the'lubricant` from said conduit and mulation -in the spherical housing I suiicient to low downward into the housin H.

What I .claim as my invention 1s: A, l. The combination with ber and a downwardly-inclined power transmission shaft, of a luniversal coupling for connecting said shaft and said drivin member including a cup, and means for ceding lubricant tol said coupling, said cup being secured to rotate with said downwardly/*in-l clined shaft and arranged .to prevent the flow of lubricant fedV to the coupling ,downl said shaft. j ,2. The combination with a substantially horizontally arranged-shaft and a downwardly-inclined 'shaft, ofa universal coupling connecting said shafts, including a cup-slllaped member forming a draining surface, f" housing surrounding said shafts and coupling having a pocket for receiving the lubricant drainage therefrom, and a drainage connection lead-` ing from said pocket. i

3., The combination j and a*downwardly-inclined` sha-ft, a vuniver-l sal` coupling connecting /said driving inem;4

.bricantpassing to theuniversal joint bepreventing any j accua driving melnlos of a driving memberA A'cant fed to said universal coupling from draining downward along the inclined shaft, a pocket for receiving the lubricant, and means for draining the lubricant from said pocket.

l. The combination with a substantially horizontally arranged shaft and a downwardly inclined shaft, of a universal coupling connecting said shafts including a socket provided with a cup-shaped member forming a draining surface,`and a housing surrounding sai-:l shafts and coupling and having a pocket for receiving the lubricant drainage therefrom.

5. The combination of a casing, a substan tially horizontally-arranged drive shaft therein, a universal coupling connecting said shafts, means for feeding lubricant to` the coupling, means for preventing lubricant fed to said universal Coupling from draining downward along the inclined shaft, a pocket for rcceivingthe lubricant, and means for draining the lubricant from said pocket into saidcasing.

6. The combination with a substantially horizontally arranged drive shaft and a downwardly inclined power transmission shaft, of a universal coupling connecting said shafts including a cup secured to said inclined shaft and having a flared end forming al guard preventing the flow of lubricant down the inclined shaft, a housing surrounding said shafts and coupling having a pocket for receiving the lubricant drainage, and a drain connection communicating with said pocket.

7. lhe combination with an engine casing, of a fly-wheel therein, a drive shaft connected therewith, a downwardly inclined transmissionshaft, a universal coupling connecting said Eshafts, means for preventing lubricant \on said universal coupling from draining downward along the inclined shaft, a pocket for receiving the lubricant drainage from said coupling, and a conduit connecting said pocket having its discharge end adjacent to said fly-wheel.

8. The combination with an engine casing, a fly-wheel therein, a power transmission shaft, a downwardly inclined shaft, a universal coupling connecting said shafts, a housing surrounding said shafts and cou pling provided with a lubricant receiving pocket, means vfor draining the lubricant from said coupling into said pocket, and a conduit connected with said pocket and hav ing its discharge end in proximity to said fly-wheel.

9. The combination with an engine casing, of a fly-wheel therein, a power transmission shaft, a downwardly inclined shaft, a universal coupling for said shaft including an inclosing cup secured to the downwardly inclined shaft, saidV cup serving to intercept the lubricant discharged from the coupling parts and flared to drain the lubricant away from the downwardly inclined shaft, a housing surrounding said shafts and coupling having a spherical portion forming a lubricant receiving pocket, and a conduit connecting said pocket and having its discharge end in proximity to said Hywheel, for the purpose described.

4l0. The combination with a driving meniber and a power transmission shaft, of a uni-I versal coupling for connecting said driving member and transmission shaft, saidl coupling comprising a ball upon said driving member, a cup-shaped member fitting said ball and having its neck portion secured to said transmission-shaft., and a complementary cup-shaped member having imperforate sides upon said first mentioned cup-shaped member, and means foi` feeding lubricant to said coupling. 1

In testimony whereof I aflix my signature in presence of two witnesses.
